UNITED STATES PATENT OFFICE.

STEPHEN A. CASE AND T. EMMET ALLEN, OF AMSTERDAM, YORK.

IMPROVEMENT IN srvllTHs FoReES.

Specification forming part of Letters Patent No. 117,602, dated February17, 1874; application filed January 24, 1874.

To all whom it may concern.'

Be it known that we, STEPHEN A. CASE and T. EMMET ALLEN, of Amsterdam,in the county of Montgomery and State of New York, have invented a newand valuable Improvelnient in Forges 5 and we do hereby declare and itconsists in novel means for keeping the hinged frontV of a forgecomparatively cool, and also in means for warming the air and utilizingfor blowing the fire and for warming purposes, as will be hereinafterexplained. Our main object is to dispense with the use of water forcooling the fronts of forges, and to use air in its stead, therebyobviating all the objections attending the use of water for thispurpose.

The following is a description of our inven- A tion:

In the Vannexed drawings, A designates the body of a forge, and a aopenings through the ends thereof. B is the fire-space, and() theashpit. D represents the furnace-front, which is hollow and connected,by means of tubular hinges b1 b1, to the ends c c of two pipes, b b2.The blast-pipe b leads from a suitable air-forcing engine, andcommunicates with the interior of the hinged front D by means of thelower tubular hinge bl. The pipe b2 forms a communication between theinterior of the front D and a chamber, E, on top of the forge by meansof the upper tubular hinge b1. Chamber E on top of the forge,'re ceivesthrough it the smoke-pipe F, and communicates with the ash-pit U bymeans of a descending ue, 113,-in which a suitable valve, g, is appliedfor regulating the amount of air forced into the forge.

It will be seen, from the above description, that the air which suppliescombustion is forced through thel front D to cool the same, thencethrough the top chamber E, and,

through pipe b3, into the ash-pit, thus giving.

a hot blast. The air, thus highly heated, may also be used for warmingpurposes generally by conducting it out of the chamber E through a pipe,e, and conveying it wherever desired.

What we claim as new, and desire to secure by Letters Patent, is-

1. The tubular hinge of the front D, connected to air-pipes b b2 of aforge, substantially as described.

2. The airchamber E, communicating with the hollow front D and with theash-pit of the forge, as and for the purpose specied.

In testimony that we claim the above we have hereunto subscribed ournames `in the presence of two witnesses.
